// checkstardone.C
// ===============
//
// check the availability of the star files for one sequence:
// if star has been executed successfully, this information has been inserted
// into the database (SequenceProcessStatus) with this macro this information
// is checked 
//
// executing the macro:
//  .x checkstardone.C+("sequencenumber")
//
// the macro returns 0, if for the sequence star is not done, and 1 if star
// has been done
// the return value is checked by the script, that executes the macro
//
// this macro is very similar to the macro checkfileavail.C
//
